COMBINATION ORGAN-STOP ACTION.

Application filed October 9, 1915.

To all iokom it may concern:

character indicated'by which various combinations of stops can be set up by theoperator and whereby the combinations canv be readily and quickly made to conform to the particular music to be played.

In the drawings accompanying and forming part of the present application, I have represented in detail one of the forms of embodiment of fny invention and have fully described the illustrated embodiment of my invention in the ensuing specification to enable those skilled in the art to practise the same. I do not of course restrict myself to this particular disclosure as I may depart therefrom in various respects within the invention as defined in the following specification and in the appended claims.

In systems heretofore proposed, which have been of the pneumatic or mechanical type, a great amountof mechanical apparatus has been necessary, which has been found unreliable .in some respects due to its complications. To obviate the above objections, I have produced an electromagnetically operated device of theelass .described which v embodies desirable features and advantages all in a simple, efficient, and economical manner, reference being had to the accompanying drawings, forming a part hereof in which the same reference characters indicate like parts throughout the several views, and in which:

Figure l-shows a side view of one form Specification of Letters Patent.

Serial No. 54,941.

the connecting apparatus necessary to connect a plurality of stops in a plurality of different combinations.

Fig. 5 shows the same circuit arrangement as is shown in combination A in Fig. 4, but with the stop keys X and Z in a position ready to be brought on by depressing key 66, that is, the stop keys X and Z andtheir assoclated magnets 59 and 60 are in position to be operated to form one stop combination.

6 shows substantially the same circult arrangement as is shown in Fig. 5, but with the magnets 60 of stop keys X and Z of combination A shown in their operated positions, following the actuation and re lease of key 66.

In a pipe organ there are what are commonly known as stop keys and I provide means whereby these stop keys can be electromagnetically operated in different combinations by the operator who .may at one time effect the action of but a single stop key, while just using this operation the operator may effect the action of a large number of stop keys.

Referring more particularly to Figs. 1, 2 and 3, which show a stop or stop lever or briefly stop key adapted to operate in conjunction with the circuit arrangement of my invention; the stop key comprises apivotally supported shaft 2 resting in grooves 3 of the supports 4:. Theshaft 2 is provided with a sleeve 5 which is adapted to fit into a recess 6 cut in the lever l. The supports 4 securely fit in grooves cut in the block 8. A snap spring 9 is provided slotted at its upper end and rests in a groove in screw 10, which screw is threaded into the strip 11 which is secured to the face of the organ frame 12 by Ineans of screws or in any suitable manner. The lower end of the spring 9 rests in a groove 14 cut in lever 1, the said groove being so positioned that when the lever is in a normal position the portion of the spring 9 bearing in groove ll is to the right of a line drawn from the shaft 2 to the slot in the screw tending to force the lever in a clockwise direction about the pin 2 as an axis. If the lever is pressed downwardly at its forward end as soon as the slot 14 has advanced to a position on the opposite side of the previously referred to line.

A I Wound electromagnetic solenoid 18 which is I by the said spring 9, it will be quickly moved to its on position as shown in Fig. 3. Likewise when the lever is moved upwardly from its on position, the spring 9 tends to snap it into its off position. In this way the lever is moved into its oil and on positions by a quiogk movement and then held therein. I pro ide' a pad of felt 15, or some other sultable material for arresting the lever 1 when it moves from its on to its ofi position, and a similar pad 16 for arresting the said lever when it moves from its off to its on position. As abovednentioned, the lever may be either manually or electro-magnetically operated. For the latter purpose, I provide a double inclosed in a shell 19 that is securely fastened toan angularly shaped iron 20. The angu larly shaped iron 20 is fastened to the member 8 by means of screws 25 and is so mounted asto holdthe plunger 26 of the solenoid 18 in position to actuate the lever 1. A screw28 is provided mechanically connecting the plunger 26 of the solenoid to the, stop lever 1. A pair of felt washers 30 are provided one mounted intermediate the head of the screw 28 and the lever 1, the other mounted between the lever 1 and the lock nut 31, which is provided for securely hold ing the screw- 28 in its adjusted position. The solenoid 18 is so arranged that when one of its windings is energized the plunger- 26.is drawn in and operates to move the lever 1 about its pivot point causing it to be restored to its off position while if the other of said windings is energized the plunger 26 is forced forward and operates to move the lever 1 from its off to its on position. The solenoid 18 also controls a set of contact springs C through the medium of the stud 33 which is carried by the snap spring 9. The set. of contact springs G are mounted .uponthe angularly shaped arm 20 by means of screws 36 and are insulated from each other and from the said arm 20 by means of strips or blocks of insulation 37.

Assuming now that the parts are in off position, should the lever 1 be operated as springs will be hereinafter described when a detailed'description of the circuit arrangements of Fig. 4 is given. I have referred tothe method of moving the parts from one position to the other by the manual actuation of the lever. These parts may also be operated by the solenoid 18. If the parts are to be moved from their 0E to their on position, a circuit is closed through one of the windings of,the solenoid, thus causing it to energize and to operate the plunger 26, thereby moving the lever 1 from its off to its on position and at the same time operating the member or stud 33, causing it to move from its oil to its on position, and to operate the group of contact springs C. With the parts in their on position, it, will be apparent that they may be restored to their oil position either manually or bymeans of the double wound solenoid, this operation -being apparent from the foregoing description.

Referring now more particularly to Fig. 4, I here show three stops X, Y and Z each of which is similar in construction to the stop shown in Figs. 1, 2 and 3 and I also show apparatus for connecting these stops in two different so-called combinations A and B. I so arrange the apparatus that ..a setof combinations may be very readily and quickly changed to an entirely difierent set of combinations. For example one piece ofmusic may require in its execution cer-- tain combinations; while another piece may necessitate entirely different combinations. However, it is to be understood that any number of stops and any number of combinations may be provided for. Each stop 3 key is provided with setsof springs such as 52, 51 and 50, and each key is provided with as many sets of springs as there are different combinationsthat the key may be included in. In the drawing, stop key X is shown provided with three'sets of springs, thereby permitting this key to be included in three different combinations. Associated with each ,stop for each different combination is a pair of coiiperating magnets 59 and 60. The armatures ofthese magnets are mechanically related to each other so that when the armature of magnet 60 is attracted, the hook pring 61 is released from contact with sprmg 62 into engagement with spring 63, and at the same time the'hook spring 61 locks the armature of magnet 60in its'ac 'tuated position independent of the energizing current" of said relay. To restore the armature of magnet 60 to its normal position a circuitis closed through magnet 59 which operates through the medium of its armature 64 to raise the hook lever 61 from engagement with the armature of magnet 60, thus releasing the said armature and allowing it to return to normal and at the same tlme the hook lever 61 dlsengages contact.

spring 63 and engages. contact spring 62. A

setting key 66 is provided for initially settingandfor operating the stops in any one desired combination. As many setting keys 66 are provided as combination are desired, two being shown, one for combination A and the other for combination 13. Associated with each setting key 66 is apair of cooperating magnets 67 and 68 whose armatures cooperate in the same manner as described for magnets 59 and 60. The magnets 67 and 59 areonly energized when a restoring key 71 is actuated. A slow acting relay 69 and a relay 70- are also associated with each of the said keys 66, whose functions will hereinafter be described. I also provide a restoring key 71 for energizing the magnets 59 and 67 to destroy the set up combinations and to restore the armatures of relays 60 and 68 to normal. If it is so desired a restoring key 71 may be provided for each combination instead of one restoring key for all the different combinations. While I have shown several different batteries, it is to be understood that in practice these will all be one and the same battery.

7 Referring to Fig. 4:, it will be seen that I provide for each stop, such as X, Y or Z, a pair of cooperating magnets 59 and- 60 for each desired combination, such as combina tions A and B.

Having given a brief'description of the apparatus involved in my invention, the detail operation of the same will now be given. Assuming that the operator desires to set up a combination (using the apparatus of combination A) in which stops X and Z are always to assume their on positions and stop Y its off position, the operator will first arrange these stops so that whenever this combination of stops is desired she may obtain it by actuating the stop setting key 66. To obtain this combination,.the levers 1 of the stops X and Z are first manually set in their on positions (as shown in Fig. 3) then the stop setting key 66 is actuated. Upon the operation of key 66 a circuit is closed, traced from battery through the slow acting relay 69, contact 7 5 and hook lever 76 and through the actuated key 66 to ground. Relay 69 is immediately energized, closing switch 78, and remains energized for ashort'interval after its circuit is broken due to its being a slow acting relay. The operator now releases key- 66 thereby momentarily closing an energizing circuit through the magnet 68 associated with the" setting key 66 (of combination A) and through the magnets 60 associated with the actuatedstops X and Z.

The circuit for the magnet 60 of the unactuated stop Y is open at its contact 55 and is therefore not operated at this time. The circuits for the magnets 60 associated with stops X and Z may be traced from ground through the setting key 66, its contact 75, contact 78 of slow acting relay 69, over conductor 78, through the multiply-connected windings of magnets 60 associated with the said stops X and Z and through springs 55 and 52 of stops X and Z- to battery. The

magnets 60, upon energizing, allow the hook levers 61 to lock their armatures in their actuated positions. The holding of the armatures 60 in this position allows contact levers 61 to engage contact springs 63. The above referred to circuit for relay 68 which is closed when the operator releases the setting key 66, may be traced from battery through the winding of said relay, alternate contact 78 of relay 69 and through contact 75 and setting key 66 to ground. Relay 68, upon energizing, locks its armature in its actuated position thereby allowing the hook lever 76 to engage contact spring 77. The setting of the stops for the second combination B is performed in the same manner as just described for the setting of the stops for the first combination A, that is, the desired stops are manually actuated and then. the setting key 66, associated with the combination, is operated. Should the operator-now at any time desire to brin on any one of the set-up combinations 0 stops, no matter in what posi tion the stops may be at the-time, she may, by'operating the setting key, associated with the desired combinatiomactuate the stops to cause them to assume their set-up position. That is, assuming that the key of combination A is actuated, the stops X and Z are returned to their on position no matter in what position they may be, and the stop Y is restored to its off position if it should be in its on position. The operation of key 66, of combination A, closes a circuit through its associated contact controlling relay 70, which may be traced from battery through the windmg of said relay, contact spring 77, hook lever 76 and the said actuated key 66 to ground, thus causing the said relay to energize. First assuming that the stops X and Z are in off position and the sto tion 0 relay 70 closes a circuit through windings 80 of the solenoids of stops X and Z and through windin 81 of the solenoid of stop Y. The circuits or the windings 80 of stops X and Z may be-traced from battery through contact springs 52 and 56, through the said windings 80 through springs 63, and hook levers 61 of magnets60 and through alternate contacts 82 and 83 to ground, thus causing the solenoids of the stops X and Z to be energized and to restore the stops to off position. The circuit for the winding 80 of the solenoid of the stop Y may be traced from battery through springs 52 and 55, said winding 81, springs 62, hook lever 61 of relay 60 and through alternate contact 84 to ground.'

The solenoid for the stop Y is" actuated to restore the said stop to off position. If the stop Y had been in its off position when the setting button 66, of combination A, was operated, the winding 81 would not have Y is in on position, the energizawas operated, its winding 80 would not have been energized as its circuit would have been opened at its contact 56. If the operator should now desire to use the combination of stops in the B combination, she would operate the setting button 66 associated with the I B combination and thereby cause the stops to return to the position selected at the time that the B combination was set up.

If it is desired to change the combinations A and B, the restoring button 71 is operated thereby closing circuits through the resetting magnet 67 of each of the diflerent combinations and through the magnets 59 of all the different combinations. The magnets 67, upon energizing, allow the armatures of the magnets 68 to return to normal thereby breaking contact between the hook levers- 76, and the spring contacts 77, and at the same time closing contact between the said hook levers 76 and springs 75, while the operations of magnets 59 restore the armatures of the magnets 60 to normal and thereby close connections between their contact springs 62 and the hook levers 61, thus retillrning the associated apparatus to norma Although I- have 'shown only three stops and the necessary apparatus for'connecting 4 these stops in two difl'erent combinations, it is apparent that any number of stops may be connected in any numberof different combinations simply by providing duplicate apparatus of the type above described.

While I have illustrated the apparatus of my invention in one specific manner, I do not wish to be limited -to the exact structure as shown, as many changes and modifications readily suggest themselves to one skilled in the art as .for example, instead of providing a resetting magnet 59 for each magnet 60 of a combination, one magnet may be used to accomplish thisresult, therefore I wish to cover all such changes and modifications as come within the spirit and scope of the appended claims;
